SPECIFICATION formingxpart of Letters Patent No. 241,442, dated May 10,1881. Application filed September-'29, 1879.

To all whom it may concern:

Be it known that I, DA IELS. S'rovER, of Freeport, county of Stephenson,and State of Illinois, have invented certain new and useful 5Improvements in IVire- Barbing Machines and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming a part of thisspecification, and

This invention relates to certain improvements in wire-barbing machines,and is an im- 0 provement on a machine for which Letters Patent of theUnited States were granted to me October 23, 1877.

The invention consists in the combination of mechanism so constructedand arranged,

5 as hereinafter described, that barbs may be wrapped upon one wire,said barbs cut by a continuous and automatic operation, and that, too,while the longitudinal or main wire or Wires is or are moving forwardwith a uniform speed, although the barb-wire is fed intermittently.

Fig. 9 represents an I It also consistsin the combination of afriction-roller and plates, as hereinafter described, for holdingandproperly conducting the barbed wire from the point at which the barbsare wrapped upon the wire to where the two wires are intertwisted, andalso in an adjustable guide for conducting the main wires in between thefeed-rolls, and of an eccentric device for raising and lowering theupper feed-roll, so as to allow of theinsertion of the ends of the mainwires between therolls, and to produce a greater or less friction uponsaid wires to properly feed the wires forward into the machine, aswillbe hereinafter more fully described.

To enable those skilled in the art to which my invention belongs to makeand use the same, I will proceed to describe it more in detail.

In the drawings, E represents the frame-wor k of the machine, which issecured to a section of d ioring or base.

G represents the bed-plate of the machine, which is slotted out toreceive the difierent portions of said machine which project below theupper surface-line of the bed-plate, and is also provided withdownwardlyprojecting bearing or hanger parts GG ,in thelowerends ofwhich are fitted to turn the ends of a rock-shaft, H, to which the lowerend of the rocking head M, which supports the barb cutting and feeding8o mechanism, is attached.

, I represents the main driving-wheel of the machine, which is securedto the end of a horizontal shaft, J, arranged to turn in bearings J J,secured to the bed-plate G of the machine.

Driving-power may be imparted to wheel I by proper connection with anysuitable and convenientdriving mechanism arranged above or below theflooring.

Upon horizontal shaft J are also secured cams K and L, the former beingarranged to operate block or head M, before referred to, upon which thebarb-wire feeding and cutting mechanism isarrangedand secured, and thelatter to operate the block or head S, upon which the barb wrapper orcoiling device of the machine is arranged, both of said blocks or headsbeing arranged to rock back and forth, as hereinafter described.

Bevel-gear N and small spur-gear O are also secured upon driving-shaftJ. Bevel-gear N is for the purpose of engaging with and driving acorresponding beveled gear, N, secured upon the end of a horizontalshaft, P, arranged to turn in suitable bearings, P P, secured tobedplate Gr. Upon said shaft P are also secured a large spur-gear, Q,and a cam, R. Spur-gear Q is for the purpose of operating theharbwrapping spindle S, which is arranged to turn in the upper part ofrocking arm S, being provided with teeth a, which engage with the teethct upon spur-gearQ. Said wrapper is also pro vided with a pin or lug, b,which catches and wraps the barb-wire 3 about the main wire 1 to formthe barb, as hereinafter more fully described. v

The feed-rolls T T are operated by means of spur-gear 0, throughspur-gear U, arranged to turn upon a suitable bearing secured to bed G,spur-gear U, secured upon the outer end of the shaft V of thelowerfeed-rolls,.TT, spur-gear W, also secured upon shaft V, and spur-gear W,secured to the shaft V of the upper feedrolls, T T.

Shafts V V are arranged to turn in suitable bearings formed in sidesupports or standards, V V secured to bed-plate G.

The upper feed-rolls, T '1", are formed upon the ends of a cylindricalsleeve or barrel, T, which, with the parts connected therewith, arefitted to turn loosely upon an eccentric-shaft, V. Thus by turning shaftV, which may be done by means of a hand-lever, V secured to the end ofthe shaft, an eccentric motion is imparted to the feed-rolls to slightlyraise the same. when desired, for the purpose of inserting the ends ofthe wires between said feedrolls.

The necessary pressure upon the wires to properly feed them forward intothe machine may be produced by means of a strong spring, X, or othersuitable spring or device for depressing the ends of the eccentric-shaftV.

Y represents an adjustable guide, provided with holes 0 c for thepassage of the wires, and

which may be adjusted laterally by means of turning nutsd d, so as toproperly guide the wires in between the feed-rolls T T, should suchadjustment become necessary, as the rolls become worn away at one pointby longusage.

(Jam It upon shaft P is for the purpose of operating at each revolutionof shaft P the barb-wire feeding and cutting mechanism of the machine,which operation is performed in the following manner: Upon swingingblock or head M are arranged to turn two feed-wheels, Z Z, and to thehub or side of the lower and larger feed-wheel, Z, a ratchet-wheel, e,is secured, and a swinging arm, f, is arranged to turn upon the shaft ofthe same. Upon the inner side of the rear end of swinging arm f, andarranged to catch into the teeth of ratchetwheel 6, is hinged a ratchetpawl or dog, g, which is pressed down so as to catch into the teeth ofwheel 6 by means of a spring, h, which is secured above said pawl or dogto swinging arm f. The forward end, f, of swinging arm f is made to bearconstantly against the peripheryv of cam R by means of a spiral or otherspring, 70, secured at one end to the rear lower end of swinging arm fand the other end to the part G of bed Gr. Driving-power is impartedfrom the lower feed-wheel, Z, to the upper one, Z, by means .of aspur-gear, l, secured in this instance to the side of said feed-wheel Z,which engages with another spur-gear, m, secured to the side offeed-wheel Z. The upper feed-roll, Z, is arranged to turn upona loose angular-shaped spindle, n, which is held in position vertically by meansof a cam-lever, o, hinged at the point 0 to block or head M, andlongitudinally by the form of the spindle, and the rear end of the samebeing also hinged to block or head M at p. The lower end of lever 0 iscam-shaped, and a flat upwardly-curved s rin 0 is arran ed between saidcam and the top of spindle n, so that when lever 0 is swung over in thedirection shown by Fig. 3 of the drawings said spring is depressed,thereby forcing the feed-wheel Z to press with sufficient power upon thetop of the barb-wire to properly feed the latter forward when the rollsare in motion. Supposing the lever 0 to be in the last-named position,from the foregoing-described construction and arrangement of the feedingmechanism it will be seen that by now rotating cam R from right to left(the direction in which the machine rotates it) it is brought in contactwith the forward end, f, of swingingarm f, depressingthe same, andthereby raising its rear end, which causes pawl or dog gto catch intoone of the notchesin ratchetwheel 6 and turning the latter, with itsfeedwheel Z and Z, as before explained, thus feeding the barb-wireforward the distance that cam It causes the peripheries of feed-wheels Zand Z to travel. Cam R is made with two slots, R and R one of which isjust suflicient to allow its beingslipped over shaft P, and the other ofthe proper width to receive the adjustingscrew R by means of which thecam is secured to the side of the cog-wheel Q. By this construction andarrangement of parts cam it can be quickly removed by removing screw Rand can also be readily adjusted to give a greater or less throw ormotion to arm f by simply loosening holding-screw R and moving thecam Rout from or toward shaft P, as the case may be, and then tightening upscrew R again, which latter, together with the support which the forkedends of cam R receive from shaft P, insures the holding of cam B in aperfeet manner during the operation of the machine.

in this instance cam R is made shell form on its outside. Therebylightness and strength are combined, and such a construction and arrangement of parts obtained as enables the operator to adjust the barb-feedvery accurately, and which shouldfeed the barb-wire forward a sufficientdistance to allow ofits being wrapped twice around the main wire 1,leaving a sufficientlength at each end, when out off, to form the barbs.The stationary cutter q of the machine is arranged in a stationaryblock, 4, formed upon ICO or secured to bed-plate G. Saidcutter may beadj ustedlaterally by means of adjustin g-screws s s and longitudinallyby means'ot' a screw, t. (See Fig. 4)

The movable cutter u is arranged in swinging block or head M,and mayalso be adjusted laterally and vertically'by means of screws 11 v andlongitudinally by means of a screw, 20.

Cams K and L on driving-shaft J are relatively formed and arranged togive to their respective swinging heads or blocks variable motions.

The form of cam L causes the end of the wrapping-spindle S to keep alittle in advance ot'the movable cutteruuntil the barb is wrapped aboutthe main wire 1 by the wrapping pin or In g b,when it then retreats, andthe cutter c'ontinues to advance until the barb is cut by its passingover the edge of the stationary cutter q. Spur-gear Q, is made broad.whereby teeth at always remain in mesh therewith, although having aforward-and-backward motion with 1 wrapping-spindle S.

Swinging block or head M and the-arm S, upon which the wrapping-spindleS is arranged, are caused to constantly press against their respeetivecams K and L by means of flat springs K and L, secured to cross-bar E,which is, in turn, secured to frame E.

In order that the wire may be out upon an angle so as to form a pointedbarb, such as shown in Figs. 6 and 7, the barb-wire rest or anvil infront of the stationary cutter q is inclined downward from the main wire1 toward the feed-rolls Z Z; and in order to keep the wire down inposition for obtaining such a cut, a holding-guide, as, provided with ahole, y, for

the passage of the wire, and hinged upon the end of a swinging lever, z,fulcrumed at the point4, is provided. Said guide is arranged to pressupon the wire at the time it is being cut by the outer end,z, which iscurved down, as represented in Fig. 2, bearing upon a roll, 5, arrangedto turn upon the end of arm 6, which is secured to bed-plate Gr, thusacting as a cam to depress said guide at.

The outer curved end, 2, of swinging lever z is made to bear upon theperiphery of roll 5 by means of a spiral spring, 7, one end of which issecured to the upper end of swinging guide 00, and the other end to theend of an upward] y and outwardly projecting arm, 8, secured to the topof swinging block or head M. By this 5 cilitated by the barb-wire beingheld perfectly arrangement of spring 7 ,which forces the lower end ofthe guide in toward swinging block or head M, the guide is made to servethe purpose not only of holding the wire in position while being cut,but also topress it against the end of spindle S during'the wrappingoperation, thereby insuring the catching of the wire by the wrapping-pin'b. t

The wrapping operation is still further fataut and secure during saidoperation from drawing forward through the feed-rolls by being pinchedat9, where it is guided into the machine from the reel. Any suitabledevice for this purpose may be employed. In this instance a lever, 9, isused, which is hinged at the point 10, and held down by a flat spring,11, underneath, being raised during the feeding operation by a cam, 12,secured upon driving-shaft J. The pressure upon the wire may be variedby means of an adjusting-screw, 13. If such an arrangement were notprovided, the process of wrapping the barb about the main wire would beimperfect, inasmuch as the wire would draw forward and become slack,thereby producing uneven and imperfect barbs.

The barb-wire 3 passes over the main wire 1, and is wrapped around thelatter from right to left toward the end of the spindle. In ordertthatit may be properly wrapped Without binding, the cam L, operating saidspindle, is formed so as to move the latter forward a little slower thanthe wire 1 is fed forward by its feed-rolls T T, since, if they moveforward with the same velocity, it will be seen that each coil would beliable to be lapped over or covered by the succeeding one, therebyproducing unsatisfactory results.

The barbed wire 1 is guided and kept in position so as not to catch andbecome retarded in its forward movement from where the barbs are put onto where the Wires 1 and 2 are twisted together, first by a wheel orroll, 14,

pressing upon the Wire, which is arranged to turn upon the end ofaswinging arm, 15, hinged at 16, and held down by a flat spring, 17,secured at the point 18, and then by passing through a flatrectangular-shaped slot or opening, 19, (see Figs. 4 and 5,) formed bythe sides '20 ot' angular-shaped block 21 and plates 22 and 23, theformer being fitted in the bottom of slot 19, formed in angular-shapedblock 21, and extendingforward nearly to roll 14, and the latter overthe top of said slot and extending forward, as represented in Fig. 4. Bythis arrangement the wire and its barbs are prevented from turningbetween the points mentioned, thereby effectually insuring the propermovement of the same.

Plate 23 is fitted loosely and held in position by a clamp, 24, thusallowing of its ready re- .moval when desired.

In order that the main wire 1 may come at the proper level for cuttingthe barbs by cutters to and q, a groove, 25, (see Fig. 1,) is formedunder the wire, extending to slot 19 in block 21, which also serves toassist in keeping the barbed wire in its proper position as it movesforward. a

26 is an angular plate securedto the top of block 0", which fits overthe end of wrappingspindle S during the latter part of the wrappingoperation, and serves to prevent the barb from being drawn back by thewrapping-pin I) when head or block S, which supports the wrappingdevice, recedes.

The driving-pulley I, which in this instance is secured to shaft J so asto turn loosely thereon, except when clutched to hub 1 fast on shaft J,may be clutched or unclutched to or from hub 1 fast on shaft J, or anyother convenient mode of communicating the driving-power may be adopted.In this instance, as before stated, a clutch device is used for thatpurpose and operated by sliding arm 27 and lever 27.

The operation of the machine may be briefly summed up thus: Having putthe machine in operation, the attendant first raises feed-rolls T T, asbefore explained, then inserts the end of wire lthrough its hole inguide y, and pushes it forward between its feed-rolls through the holein the wrapping or barbing tube S, thence on under roll 14 and betweenplates 22 and 23 to the rear of the barbin g part of the machine. Hethen lowers the upper feed-rolls, T T, after which he passes the end ofthe barbwire 3 through a hole in guide-piece 9 and.under clamping-lever9, thence forward between its feed-rolls Z Z, through swinging guide at,

I and into position, as indicated in Fig. 3 of the drawings; then startsthe machine, taking hold of the end of wire 1, drawing it withsufficient tension to keep it taut until a sufficient length of wire hasbeen barbed to enable him to fasten the end to the spool of the spooler,when the machine is stopped,and the attendant raises feed-rolls T Tagain and takes the en d of wire 2 and passes it through its hole 0 inguide Y, and thence between the feed-rolls and forward upon the outsideof guide-roll 66, arranged upon standard 67, and upon the inside ofanother guide-roll, 68, upon plate 23, thence forward over the sprocketsof the sprocket-wheel of the spoofing-machine with wire 1, and fastensit to the spool to which wire 1 has already been fastened. Thefeed-rolls are new lowered and drive-wheel I unclutched, when thetwister part of the machine is started and allowed to run until the twowires are properly twisted together between the sprocket-wheel and thebarbing part of the machine, after which driving-wheel I is thrown intoclutch, and the machine is then in full operation, the main wires 1 and2 being drawn from .their respective reels or spools, supported uponsuitable stands arranged at proper distances from the machine, and thebarb-wire also drawn from a spool or reel supported in a similar manner.

It frequently happens during the operation of a wire-barbing machinethat one ofthe main wires breaks or is found defective, so that a piecehas to be cut out; and to expedite the operation of securing the ends ofthe wires together when thus cut or broken, and also when the end of anew reel or coil of wire, 1 or 2, is to be connected to the end of thecoil run out, a wire-splicing machine, F, is attached to myinachine,.and which wire-splicing device-is constructed as follows: Ashort hollow shaft, 69, provided with a slot, 73, and withturninghandles 70, is arranged to turn in bearings formed in the upperends of upright side supports or standards; 7l 71, which are alsoprovided with slots 73 73, and to the outer sides of said standards 7171 are secured two other stationary holding-pieces, 72 72, provided withslots 72 72. In splicing two ends of wire to gether hollow shaft 69 isturned to bring its slot in line with the slots 73 and 72, as indicatedin the drawings, and then the wires are placed in said slot with onewire lapped or placed over the other, the ends of the wires being lappedand extending in opposite directions, the end of each wire extending ashort distance beyond its respective end of the device, and in which itis held from turning or twisting about the other end of the wire, sinceslots 72 are only wide enough to receive a single strand of wire.

The center of slotted shaft 69 is provided with a set of holding jaws orteeth, 74, which are set just far enough apart to leave a slotcorresponding to-the width of the slots 72. Consequently, when tubularshaft 69 is rotated .by means of handles 70, the wires will be carriedaround by the jaws or teeth 74' and the ends of the wires twistedtogether on each side of said teeth or jaws, such twists extending fromthe sides of the jaws or teeth 74 in opposite directions to the innersides of slotted pieces 72. After the ends of the wires have beentwisted together, as above described, by means of this splicing device,the attendant turns tubular shaft 69 so as to bring the slots all inline again, after which, by a slight upward pull on the wire, the latteris removed from the splicing device, the slots 73 and 73 being wideenough to allow the twisted and spliced portions of the wires to belifted out or withdrawl'l freely.

Those skilled in the art to which my invention belongs will readilyperceive and understand the practical advantages necessarily resultingfrom my present invention. The main wires 1 and 2 having a continuousand uniform longitudinal or forward motion during the operation of themachine, all the noise; and straining of the parts of the machineincident to or resulting from the constant stopping and starting ofthemain wires, or the parts which feed them forward, are obviated by myimprovements hereinbefore described, while at the same time theimprovements referred to render the operation of barbing, twisting, andspooling the wire very expeditious and uniform.

Having described my improvements in wire barbing, twisting, and spoolingmachines, what I claim therein as new and of my invention, and desire tosecure by Letters Patent, 1s
